Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in the filling valve section of an apparatus for filling a liquid such as juice into a container such as a can that has been filled with a floatable solid such as tangerine sandbags in advance.

BACKGROUND OF THE INVENTION Currently, devices for filling containers such as cans with liquids such as juice are equipped with a liquid filling section including a valve section as shown in FIGS. 1, 2, and 3.

Figure 1 is a half-cut cross-sectional view of the filling part immediately before or after filling the can with liquid, and Figure 2 is a half-cut sectional view of the filling part of the same device while the lid is injecting liquid at the top dead center. FIG. 3 is an enlarged sectional view of the filling valve section shown in FIGS. 1 and 2. FIG.

This liquid filling portion beam cover 6 is provided coaxially with the filling valve portion A and below the filling valve portion A.

This filling valve part A has a degassing pipe 2 in the center and a liquid supply cylinder 3 with a vertical cylindrical part 31 at the lower end.

The degassing pipe 2 has a protruding part 21 that protrudes downward from the vertical cylindrical part 31, and has a valve seat 23 having a conical outer surface 22 at the lower end of the protruding part 21, and a lower end surface of the valve seat 23. It has an air passage 25 in the center that opens to 24.

Further, this filling valve part A has an inner surface 41 that slides in a liquid-tight manner on the outer surface 32 of the vertical cylindrical portion 31 of the liquid supply tube 3, and has a valve seat 2.
Valve body 4 having a sealing surface 42 at the bottom that sits on the outer surface 22 of Valve body 3
It is equipped with

The valve body 4 is provided with an annular elastic body 43 at a position where the open end 11 of the iron body 1 contacts, and is engaged with a spring 5 above the valve body 4 and is seated on the valve seat 23 of the degassing pipe 2. I'm wearing it.

Further, the upper ends of the degassing pipe 2 and the liquid supply cylinder 3 are at atmospheric pressure, and no pressure is applied thereto.

Place the iron body 1 on the lifter 6 at the bottom dead center of the lifter 6,
The lifter 6 is raised by a cam device (not shown), the open end 11 of the iron body 1 is engaged with the annular elastic body 43 of the valve body 4 as shown in FIG. Subsequently, the valve body 4 rises, and when the valve body 4 leaves the valve seat 23 of the degassing pipe 2 and the liquid supply cylinder 3 and the inside of the mortar body 1 communicate with each other, liquid is transferred from the liquid supply cylinder 3 to the mold body 1. The liquid flows down due to its own weight and starts filling with the liquid, while the air inside the mold 1 is exhausted to the outside of the apparatus through the degassing pipe 2 in an amount equal to the volume of the liquid that has flowed in.

This filling is shown in Figure 2, and after passing through the top dead center of the lid 6,
The filling continues until the liquid supply tube 3 and the inside of the die 1 shown in FIG. 1 descend to the position of the lifter 6 where communication has started, at which point the filling ends.

The filled iron body is lowered to the bottom dead center of the lifter 6 and is discharged from the apparatus by a turret (not shown).

When mandarin juice is continuously filled at high speed into a can pre-filled with an appropriate amount of mandarin sand bags using the above-mentioned device, the liquid level of the juice may enter the air passage 25 of the degassing pipe 2 when filling is completed. Since the juice is filled until it reaches the maximum position, the tangerine sandbags floating in any can enter the air passage 25 of the degassing pipe 2, are sucked up and accumulate in the air passage 25, and gradually increase in number and fill the air passage 25. The can was almost completely blocked and acted as a resistor against the exhaust air, resulting in variations in the contents of the can.

Also, when a dispersion was discovered, the equipment was stopped and the air passage of the degassing pipe was cleaned.

The purpose of the present invention is to eliminate the above-mentioned drawbacks and to make it possible to rapidly and continuously fill a number of containers with a fixed amount of juice into cans or other containers that have been filled with an appropriate amount of suspended solids such as tangerine sandbags. An object of the present invention is to provide an improved liquid filling device that does not cause variations in the amount of product filled.

The present invention has a liquid supply cylinder having a vertical cylindrical part at the lower end, a part that passes through the vertical cylindrical part of the liquid supply cylinder and protrudes below the vertical cylindrical part, and has a part on the lower end surface of the protruding part. a degassing tube having an air passageway that opens; and a blocker having a cylindrical portion at the top that is slidable against the outer surface of the vertical cylindrical portion, and seating a valve seat formed on the outer surface of the lower end of the protruding portion of the degassing tube. A liquid filling device comprising a valve body having a surface at the bottom thereof, characterized in that a lower end surface opening of a protruding portion of the deaeration pipe is covered with a net.

Embodiments of the present invention will be described with reference to the drawings.

Fig. 4 is a cross-sectional view of the filling valve part A' according to the present invention, and Fig. 5 is a cross-sectional view of the filling part of the filling device equipped with the filling valve part A' according to the present invention, immediately after filling is completed. FIG.

The filling device of the present invention shown in FIG. 4 is shown in FIG. 3, and is a device in which a wire mesh is fixed to the deaeration pipe of the filling valve section A currently used above with a wire mesh holding ring. The entire surface of the lower end surface 24 of the valve seat 23 is covered with a circular wire mesh 7, and the inner surface 8 of the outer peripheral rising portion 81 of the wire mesh retaining ring 8 is provided with a hole 83 having a diameter larger than the inner diameter of the air passage 25 of the degassing pipe 2.
2 was fitted onto the outer peripheral step 26 of the lower end of the valve seat 23 of the deaeration pipe 2, and the wire mesh 7 was fixed to the lower end surface 24 of the deaeration pipe 2.

Using the filling valve A' equipped with the wire mesh 7 described above, tangerine juice is filled into a can filled with tangerine sandbags in the conventional manner. Immediately after, the floating sand bag B adheres to the wire mesh 7, but the iron sand bag B is absorbed by the juice C that has entered the degassing pipe 2.
flows into the iron body 1 as the lifter 6 descends,
It is washed off by the juice C into the iron body 1.

A specific example will be described here.

A wire mesh with a 1 mm square gap was attached to the degassing pipe of the filling device, whose air passage has an inner diameter of 8.7 mm, and 970 g of tangerine sand was packed in the air to a height of 133.4 m.
Mandarin orange juice was filled into a can with a diameter of 54 mm at a speed of 155 cans per minute.

As a result, the average weight of 50 cans was 246.8 g.

Also, the lightest can weighs 245g and the heaviest can weighs 249g among the 50 cans, and the variation in the amount of filling is approximately ±2.
It was g.

As shown above, even when a large number of cans pre-filled with suspended solids such as tangerine sandbags were filled with liquids such as tangerine juice at high speed, there was almost no variation in the amount filled.

Additionally, since sandbags do not get into the air passages, there is no need to stop the machine for cleaning, allowing continuous operation.
